I am a very happy XPS owner with the MR9800. But guess what, I like the Alienware Area-51m also. To me it is a toss up. Power Vs. Style and Beauty and somewhat less power. I mean not matter what the 9700 and Go5600 cannot compare to the mr9800. Not even close. And the 1920x1200 resolution must be seen to be appreciated. And also, while true the magnesium alloy is stunning, I as many XPS owners installed the new mr9800 card ourselves, and I can tell you the engineering on the XPS's internals is excellent. I mean I was impressed to see every connector inside has a pull tab so you do not damage to ribbon connector. Things like that show that Dell is trying to improve their engineering. The XPS is King in the DTR category right now. Read the Latest Maximum PC 3D magazine review. However, that being said, nothing looks as cool as the Alienware, and my solution, buy them both. hehe
Seriously, I will get one within the next few months. I love MY XPS, but am intrigued by the Alienware. Hey this is America. Save your $ and get both if you like. I say, either way, you cannot go wrong.
Laptops sure have come a long way.
